He said,speaking about the change in constitution is a deviate topic. In the past some in the opposition had called for a referendum on changing the constitution.Mr. Khatami however about an article in the constitution on the "power of president" attacked at the fundamentalists in the regime who ask for limiting the power and responsibility of the president. The current political situation in Iran is that , now that Mr. Hasan Rohani become the president , Iranian people are watching him to see what he can and can not do?? !!!! And who has the real power in the Islamic Regime in Iran? If the trend become in a way that regime can not continue the past eight years of Ahmadinejad, then the years ahead must prove and guarantee the future Government by Islamic reformists and moderates and not anymore the fundamentalists. This is what worries the Iranian people ,the fear of yet another Ahmadinejad style of Government and Khamenei's support for them.!!!????
